Bug: a course with no grade data prevents subsequent course data from displaying

[g-luo]

This course has no data, yet it shows up in grades

[THE-COB]

I don't see this showing up in grades anymore

I am still able to replicate this issue. In addition to COMPSCI C182 lacking grade data, I was unable to add grade data for other classes once I had (tried to) add COMPSCI C182. For example, below is what I saw when I added BIO 1B, then COMPSCI C182, then BIO 1A.

The new Berkeleytime rewrite will address this issue.
